UNITED STATES CLIFFORD PETERSON, OF NEW YORK, N, Y.

TOOTHBRUSH.

Application filed July 28,

My invention relates to toothbrushes and has for its object to form apocket in the brush end thereof whereby to carry a liquid absorbentmaterial, such as for instance, a sponge, which is adapted to come intocontact with the bristles of the brush durlng its use whereby to forcethe liquid therefrom.

Another object of the inventlon is to provide means whereby theabsorbent material may be removed and replaced thereln.

A still further object is to provlde a cover plate arranged on the backofthe brush for enclosing the absorbent material within the pocket andto retain the same in operative position with respect to the bristles ofthe brush.

Other objects and advantages reside in the special construction,combination, and

arrangement of parts forming the invention,

at: more fully hereinafter described and claimed, reference being had tothe accompanying drawings forming part hereof, wherein Figure 1 is aperspective view showing the cover plate in closed position,

Figure 2 is a similar view of the brush end of the device showing thecover plate in open position,

Figure 3 is a vertical sectional view taken substantially along the line3-3 of Figure l, and

Figure 4 is a perspective view showing the brush engaging flange formedon the cover plate,

Referring now to the drawing I have shown my invention comprising abrush inchiding a handle 5 and a head 6 within which is suitably secureda set of bristles, 7, constituting the brushing element and an opening 8is arranged to extend vertically through the brush head within which maybe inserted a quantity of fluid absorbing material such as for instance,a sponge 9, the sponge being of sufficient size to extend downwardlyfrom the head between the bristles for a distance reaching almost to theend thereof.

A cover plate 10 is pivotally-mounted on a pin 11 secured to the head ofthe brush at 1927. Serial No. 209,002.

one end of the opening the other end of said cover plate having a recess12 formed therein adapted to releasably engage the stud 13 formed at theopposite end of said opening. A flange 14 is arranged at one side of thecover plate engageable with the edge of the brush head preventing thesame from being moved entirely thereacross. By moving the cover plateover the opening in the brush head so that the pin 13 will on gage therecess 12 the plate will thus be retained upon the head in longitudinalalinement therewith.

The sponge 9 may be saturated with any suitable fluid, such as forinstance, at liquid dentri'frice, and it is obvious as soon as the brushis placed in use, the pressure of the bristles against the sponge willoperate to force the liquid therefrom.

It is to be understood however, that various types of brushes may beconstructed embodying my invention as the same is not limited entirelyto use in construction to tooth brushes.

It is obvious that the invention is susceptible to various changes andmodifications without departing from the spirit of the invention or thescope of the appended claim, and I accordingly claim all such forms ofthe invention to which I am entitled.

I claim:

A brush comprising a head having a set of bristles carried thereby, saidhead having an opening extending substantially throughout its length andadapted to retain a quantity of absorbent material therein, saidmaterial extending therethrough for engagement with the bristles of thebrush, and a cover plate pivotally mounted at one end to the brush headand movable into and out of closing position with respect to saidopening and locking means for said cover plate comprising a recessformed in the free end of said plate, a pin formed on the brush headengageable therewith, and a flange arranged at one edge of the plateengageable with the edge of said head.

In testimony whereof I affix my signature.

CLIFFORD PETERSON.
